摘要: 利用描述分析和累积距平的方法对内蒙古鄂温克地区1981--2010年30年的最大冻土深度进行分析。结果表明,鄂温克地区最大冻土深度多年平均为244 cm,最大值出现在2010年,为288 cm;最小值出现在1983年,为222 cm;两者相差66cm。最大冻土深度呈逐渐增大趋势。

Abstract: The maximum frozen soil depth of the Ewenke area of Inner Mongolia from 1981 to 2010 is analyzed by way ofdescription analysis and cumulative distance. The results show that the maximum frozen soil depth in Ewenke area is 244 cm inaverage; the maximum value (288 cm) appeared in 2010, while the minimum value (222 cm) appeared in 1983; and thedifference between the maximum and minimum is 66 cm. The maximum frozen soil depth is increasing gradually.
